Gamasutra offers some calculation based on a Reddit comment by Notch where the Minecraft designer says the indie sensation sold 800,000 alpha copies and another million more since, for an estimated $33 million in gross revenue before PayPal fees, taxes, etc. Here's what he says about where this "huge wad of money" is: "It all ends up in an account somewhere, and I try not to look at it. I get a normal salary these days for day to day stuff, but there's a big pile somewhere." Thanks Joao.
